SPECIFICATION forming part of Letters Patent No. 741,137, dated October13, 1901;.

Application filed June 23, 1903.

To all whom it may concern.-

Be it known that I, FRANK J AGER, a citizen of the United States,residing at West Hoboken, county of Hudson, State of New Jersey, haveinvented certain new and useful Improvements in Artificial-Stone Tubs,of which the following is a specification.

The object of my invention is to provide a new improved artificiahstonetub which is simple in construction, light, strong, and durable,cannotcrack or warp, is not injuriously affected by acids or soaps, and is notexpensive.

In the accompanying drawings, in which like letters of referenceindicate like parts in all the figures, Figure 1 is an end view of alaundry-tub made according to my invention. Fig. 2 is a verticallongitudinal sectional View of the same. Fig. 3 is a vertical transversesectional view of the same.

The tub is constructed with two end frames A, of cast metal, cast-ironbeing preferred, which end frames are substantially U -shaped and arecurved approximately L-shaped in transverse section, with the cornersrounded more or less. Hooks B of any suitable shape are cast integralwiththe flanges of the frame and with the bottom, so as to project fromthe inner sides of said members. Said hooks are preferably formed byinserting bent and hookshaped pieces of wire into the mold before suchend pieces are cast, so that the ends of such bent wires are firmlyembedded and secured in the metal of the end frame. The side flanges ofeach end frame are connected with each other by a series of wires ormetal rods 0, the ends of which are secured on the above-mentionedhooks. The end frames A are spaced a distance apart commensurate with adesired length of the tub, and the corresponding npright flanges and thebottoms of the two end frames are also connected with each other bywires or metal rods 0', attached to the aforesaid side hooks, so thatthese wires or metal rods, with the end frames, form a metal skeletonfor the tub. A wooden top frame F is placed upon the top of this skeleton, and from the same a series of corrugated Serial No. 162,824. (Nomodel.)

pins or screws G extend downward. The metal skeleton of the tub is thenplaced into a suitable mold, and a core is placed within the skeleton,so as to form a space between them equal to a desired thickness of thewalls of the tub and within which space the tie rods or wires C G arelocated. An artificialstone compositionsuch, for example, as a mixtureof cement, fine sand, and cinders, or any other suitable stonecomposition-is then cast into the space between the mold and the coreand permitted to solidify and harden. The tie rods or wires 0 C areembedded in the walls of the tub. Before the composition of the wallshardens the wooden frame F is placed upon the metal skeleton in suchamanner that the corrugated pins or screws G pass into the upper edge ofthe still soft walls of the tub, so that when these walls harden theprojecting ends of these corrugated pins or screws will be firmlyembedded in the walls, whereby the wooden top frame is held securely onthe top of the tub.

Laundry-tubs, sinks, pickling tubs or vats, and like vessels can be madein the manner described.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

' 1. In a tub,the combination with cast-metal end frames L-shaped incross-section, of eyes projecting from the inner sides of said endframes, tie-rods uniting the flanges of the end frames and secured tosaid eyes, and tie-rods uniting the end frames at the front and rearsides and bottom of the tub, also secured to hooks in the end frames andstone composition, end, front, rear and bottom walls between and in theend frames, in which Walls the tie-rods are embedded, substantially asset forth.

2. In atub, the combination with cast-metal end frames, of hooksprojecting from the inner sides of said end frames, tie-rods uniting theflanges of the frames and uniting the two end frames at the front, rearand bottom of the tub, a wooden top frame having downwardly-projectingpins and end, front, rear and bottom walls of artificial-stonecompositwo subscribing witnesses, this 23d day of tion, in which Wallsthe said tie-rods and the May, 1903. downwardly-projecting pins of theWooden top frame are embedded, substantially as set FRANK JAGER' 5forth.

In testimony whereof I have signed my OSCAR F. GUNZ, name to thisspecification, in the presence of MARION HALL.
